New long-term data from a permafrost monitoring site in Healy, Alaska, suggest it was a net carbon source to the atmosphere at least since 2004 and, under current climate conditions as the region grows warmer, will continue to be one, potentially losing up to a fifth of all carbon stored… Read more
With intense wildfires in the western U.S. and frequent, intense hurricanes in the Gulf of Mexico, the nation is again affected by extreme weather-related events resulting from climate change. In response, cities, states and regions across the country are developing policies to reduce their emissions of greenhouse gases, chiefly carbon dioxide (CO2). Even though many state and local governments are committed to these goals, however, the emissions data they… Read more
Given the tremendous ability of forests to absorb carbon dioxide from the atmosphere, some governments are counting on planted forests as offsets for greenhouse gas emissions—a sort of climate investment. As with any investment, however, it’s important to understand the risks. If a forest goes bust—through severe droughts or wildfires, researchers say—much of… Read more
Study findings take a dramatic step towards a greenhouse gas information system that can fundamentally change the way cities, states and the nation tackle the climate change problem
Results from Northern Arizona University’s Vulcan Project estimating carbon dioxide (CO2) emissions from fossil fuel combustion for the entire U.S. show very close agreement to a new atmospheric-based approach for estimating these same emissions, as reported in a paper… Read more
As the demand for transportation fuels has plummeted at an unprecedented rate in the last month due to the COVID-19 pandemic, a Northern Arizona University scientist says the dramatic decrease in local air pollution and carbon dioxide (CO2) levels above cities is significant, measurable and could be historic, depending on how long commuters and other drivers… Read more
If the fate of carbon is a test that planet Earth is taking right now, one of the answer keys is likely to be found in soil, where microorganisms—which account for nearly 15 percent of global biomass, by some estimates—eat, store and respire carbon and other nutrients. As Earth warms, how these microbes change the way they live will have potentially big consequences for where the carbon goes.
Now, a team… Read more
